Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Incomplete verification of on-chain Schnorr key points allowed malformed consensus keys to bypass registration guards. Future updates must enforce strict canonical coordinate, on-curve, subgroup, and non-identity validations.
Denial of Service: The consensus tasks were vulnerable to remote panic-induced Denial of Service due to integer underflow when subtracting from the current view number during message validation.
Signature Validation Bypass: Lack of view binding inside signed builder fee payloads enabled signature replay attacks across different consensus views. Builder signature validation must enforce view-number binding.
